         Boy, it's REALLY clear here!  <G>

         As a comparison, my ALOHA circle runs about 200 miles most days, 
IF I elect to see the digis in New Mexico.  if I exclude the digis, I can't 
even get UI-ALOHA to generate an ALOHA circle, there are too few stations 
out this way.

         My stats currently show:

         16 mobile stations
         3 wx stations
         7 home stations
         17 digi stations

         Wow, that's a LOT.  Where do they come from?  Nevada, Utah, 
Colorado, or maybe all of these plus more?

         But the real problem isn't allowing me to use 5 hops, it's that I 
don't see anybody unless they use AT LEAST 3 hops, and at three hops it 
still isn't reliable.

         Perhaps I should add the following statement to my status text:


         Just a thought...
